直方图是用面积表示各组频数的多少，矩形的高度表示每一组的频数或频率，宽度则表示各组的组距，因此其高度与宽度均有意义。 程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。 (Histogram is that each group size the number of frequency, the height of the rectangular frequency of each group said that the number or frequency, the width of that group from each group, so the significance of height and width of both. Extraction procedures need a lot of parameters histogram features, such as mean, variance, skewness, kurtosis, energy and entropy.)

说明：  先对图像均衡化 增强对比度 加噪声 然后分别进行空域和频域滤波(First, the contrast enhanced image equalization plus noise and then separate airspace and frequency domain filtering)

说明：  对布朗运动的方程求解 是个随机微分方程 进行求解(The solution of Brownian motion is a stochastic differential equation.)

本程序可以实现具有较好相关性的ZC序列，其时频两域相关性很强(The program can achieve better correlation with the ZC sequence, time and frequency domain strong correlation)
